hello my boat was stuck in reverse, had someone work on it and now I have gear lube oil leaking from air intake holes. I think O_ringwas not replaced??? adjusted the shift cables and had muffs on it in driveway and some water was coming in back of motor now he says I have a blown freezeplug??? Was hot out and never did this before???? we took boat out and kept it on trailer (just in case) started right up no water leaked in back but still stuck in reverse!!!! really tired of boat issues, never had all these other problems before!! any help is greatly appreciated!!! thanks in advance!!!
